Michael Barone says that redistricting is about a wash this cycle, because the Pubs gained one seat net or something. No doubt that is true.
He is considering a seat as either a D or R seat, as opposed to looking at marginal seats and whether they are more marginal or not.
He also didn't understand what was done in Texas. He thinks that the intent was to link heavily Hispanic areas with heavily Republican counties. The intent of the Democrats is to link counties along the border that are 90% Hispanic with areas 100s of miles away so that the districts are still majority Hispanic.
